There are several online stores from which men can buy a watch. Stores like kohls.com, macys.com, and nordstrom.com all have sections of their websites devoted to watches. Also, websites like Amazon.com & ebay.com sell watches as well. Watches for men may be more expensive than women's watches just because men's watches typically require more material to accommodate a larger wrist size. However, watch prices will also vary depending on the quality and materials of the watch.
